Workplace Investigations

It is not uncommon for respondents to an investigation to take personal or carer’s leave (sick leave) claiming that they are suffering from stress or anxiety. If this occurs, employers need to act appropriately, but this does not necessarily involve stopping the investigation process.

Employers should:

• assess the medical evidence to ascertain the respondent’s condition and determine how long they are likely to be unwell;
• avoid exacerbating the condition;
• determine whether the employee is unfit to attend the investigation meeting;
• take into consideration the evidence of other witnesses;
• consider delaying the investigation for a short period; and
• consider conducting the interviews in other ways, for example, in writing.

While all efforts should be made to accommodate an employee who has taken personal or carer’s leave during an investigation, if the respondent does not participate in the investigation, the investigation report may be prepared based on the available evidence.

The time spent on the internal investigation by the employee should be counted as working time[1]. The general statutory and internal company principles on sick leave apply. Sick leave for which the respective employee is not responsible must generally be compensated (article 324a paragraph 1 and article 324b, Swiss Code of Obligations). During certain periods of sick leave (blocking period), the employer may not ordinarily terminate the employment contract; however, immediate termination for cause remains possible.

The duration of the blocking period depends on the employee's seniority, amounting to 30 days in the employee's first year of service, 90 days in the employee's second to ninth year of service and 180 days thereafter (article 336c paragraph 1 (lit. c), Swiss Code of Obligations).

There are circumstances of misconduct in the workplace that can also constitute criminal conduct and be subject to a criminal or regulatory investigation. This can include physical or sexual assault, theft, fraud, illegal drug use or stalking.

An employer can proceed with an investigation to determine whether the respondent engaged in misconduct on the balance of probabilities. The employer can terminate an employee’s employment before the outcome of any criminal investigation. However, the employer must keep in mind that procedural fairness must be afforded to the employee, particularly in circumstances where an employee is awaiting the outcome of a court proceeding.  

Alternatively, an employer may decide to suspend the employee pending the outcome of the criminal investigation. If a criminal act has been committed, then the employer may decide to terminate the employee’s employment.

Co-operation with the police and regulatory authorities is sensible and evidence can be compelled by the police or regulators by, for example, a subpoena, search warrant or an order for production.

The actions of the employer may carry through to a subsequent state proceeding. First and foremost, any prohibitions on the use of evidence must be considered. Whereas in civil proceedings the interest in establishing the truth must merely prevail for exploitation (article 152 paragraph 2, Swiss Civil Procedure Code), in criminal proceedings, depending on the nature of the unlawful act, there is a risk that the evidence may not be used (see question 27 and article 140 et seq, Swiss Civil Procedure Code).
